History
The Ksar of Aïn-Séfra was erected around the year 1586 by the children of Mohamed Ben-Chaïb dit Bou-Dekhil, patron saint of the city, after the purchase of the land from local tribes against 1000 sheep, according to the tales of oral tradition.
French Period
During the first French incursions in the middle of the 19th century, the majority of "Chorfa" families left the ksar as refuges, mainly to Tlemcen and Fez.
The modern city dates back to the French colonial era. Initially, in 1882, a strategic military garrison post consequent to the revolt of Sheikh Bouamama left their bastion of Figuig. French troops have instead established a military post at the site of Aïn-Séfra, to control "The Gateway to the Sahara".[1] A railway reached Aïn-Séfra as early as 1887, and it extended to Bechar and Kenadsa in 1906, both for economic and strategic reasons.
During the colonial period, it was an important sub-prefecture and a military territory, but also a region of cultural, economic and political importance. The region where Aïn-Séfra is located was one of the bastions of the popular resistance against the French colonial conquest, south of Oran.
Climate

It snowed in 1979, and in the winters of 2016/2017[1] and 2017/2018. An unusual blizzard hit the area on 20 January 2017, dumping snow in the municipality up to a meter thick in some places. This was the largest snowfall in residents' memories and had caused travel disruptions due to iced roads.[2]
